changes to drivers/scsi/sym53c8xx_defs.h in the mips tree

[Christoph Hellwig <hch@lst.de>]

Hi Carsten,

do you remember what your changes to drivers/scsi/sym53c8xx_defs.h in
the mips tree are supposed to help with?

sym53c8xx_defs.h is only used for the ncr53c8xx driver, which despite
the name is only for NCR53c720 chips these days (supported on parisc,
and eisa/mca).  It has correct big endian support for parisc alrady.

Also the patch duplicates your changelog and copyright entry that's
in the file already.
